cr125 power question and cr60 engine noise question

ok just a quick ?.my 125 makes great power low and mid but on top i think the power signs off to early,the 60 seems to have more overrev than the 125. the bike has been ported,as well as had the head shaved by procircuit. its running a procircuit pipe with the stock silencer,it had a shorty on it but i switched it out in hopes of gaining some more overrev.it also has a v-force reed valve in it.just wondering what i could do to correct this.i figure its not a motor problem such as a need for a new top end, i think it would run bad everywhere if that was the case but am not sure.ok now for the 60.when idling the bike seems to make like a tapping sound.it runs awesome has great compression and power but just want to make sure that im not flirtin with diaster here.any advice would be appreciated.
